Abstract

In this study, we investigated the Pretilt ang1e generation in nematic liquid crystal (NLC) by using the transcription, alignment on polyimide(Pl) surfaces. That the uniform alignment of NLC is observed by microphotograph textures in LC cells on Pl surface. We obtained that the pretilt angle of NLC are generated about 3.6$^{\circ}$on Pl surface. It is considered that the LC alignment by transcription alignment method is attributed to memory effect of LC on Pl surface.
